Product Description:
The FC-202P37KT6131G4330 is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. Designed for automated pump and fan systems, the unit converts fixed-frequency three-phase mains power into a regulated output that matches real-time flow or pressure demands, improving process efficiency in water treatment, irrigation, and similar installations. Within a control cabinet, it communicates with PLCs through standard I/O channels and provides braking connections for quick deceleration of high-inertia loads.
Process feedback is handled through an analog output that delivers an 8-bit signal, allowing 256 discrete steps for proportional indicators such as level or flow. The same channel maintains an accuracy of 0.8% FS, so the deviation between commanded and reported values remains small over the full scale. Command terminals accept sensors and switches operating at up to 28 V DC, protecting the internal logic from higher field voltages. On the outbound side, a transistorized digital output can source 40 mA, which is sufficient to drive relays or opto-inputs without auxiliary boosters. For high-resolution speed monitoring, the drive offers a frequency output that reaches 32 kHz, enabling tight closed-loop control by external counters when rapid state changes must be captured.
The drive has a continuous power rating of 37 kW, equivalent to 50 HP, making it suitable for midsize centrifugal pumps in municipal lift stations. A steady-state line current of 49 A supports the proper selection of contactors, cables, and thermal relays, while the 600 V voltage class matches North American 575 V networks and provides headroom for supply fluctuations. The minimum brake resistance is 17.1 Ω, and the nominal brake resistance is 23.6 Ω. These resistance values support calculations for deceleration energy when a compatible braking circuit is used. The upstream circuit requires an 80 A pre-fuse that can be integrated into standard motor control center hardware.
